420O1 420J2 Strip ea STEELS
Tlhaloso e khutšoane:
420J1 le 420J2 liliba tsa tšepe li na le mefuta e 'meli e tloaelehileng ea lisebelisoa tsa tšepe tse nang le letsoai le nang le li-stee tsa tšepe. Li na le phapang e itseng ka bokhabane le litšobotsi tsa lik'hemik'hale. Mona ke kakaretso e khuts'oane ea e 'ngoe le e' ngoe:
1. 420J1 strip ea tšepe: 420J1 ke tšepe e fokolang e nang le tšepe e se nang thuso e nang le sekhahla se phahameng le matla. Ka tloaelo sebopeho sa eona sa lik'hemik'hale hangata se kenyelletsa hofika 0.160.25% carbon, e ka bang 1% chromium, le malybemum e nyane. 420J1 e fana ka khanyetso e ntle ea ho hanyetsa, ho seha ts'ebetso le thepa ea ho tsitsa. Hangata e sebelisoa bakeng sa ho etsa lithipa, lisebelisoa tse buoang, likarolo tsa ho buoa, likarolo le lits'ebeletso tse ling tse u rorisang.
2. 420J2 Strip ea tšepe: 420J2 ke tšepe e se nang thuso ea carbon e nang le thata e phahameng ebe u roala khanyetso. Hangata sebopeho sa eona sa lik'hemik'hale hangata se na le 0.26-0.35% le carbon le hoo e ka bang 1% chromium. 420J2 e na le litaba tse phahameng tsa khabone tse hahiloeng li bapisoa le 420J1, li hlahisa thata le ho khaola ts'ebetso. Hangata e sebelisoa khafetsa bakeng sa ho etsa li-kish, liletsa tsa ho buoa, liliba le likarolo tse ling tsa mochini.
